The course turned out to exceed all my expectations. What started as an attempt to write a sole ebook about state management in React with Redux and MobX, turned out into a full blown course with a page ebook, exciting applications and boilerplate projects to get started in learning and building applications with these libraries, and screencast series about implementing React applications from scratch with state management. The bigger idea was to built a course that gives learners a consistent way to study the topic state management. I had the feeling that there exist way too many, partly inconsistent or outdated, tutorials around these topics and it is hard for learners to choose from so many opportunities. I thought, one well structured course should help newcomers to get started easily in the topic of state management with React's local state, Redux and MobX. The course teaches you how to use local state in React and scaling React applications with advanced practices, patterns and techniques. Afterward, the ebook dives into learning Redux and MobX as libraries for state management.

It is only the view layer with local state management.

The book dives deeply into state management in React. You will learn everything about React's local state and state management with Redux and MobX. It comes with a lot of best practices, techniques and concepts. Along the way you will have practical hands on experiences by building own applications. The book turned out to exceed all my expectations. What started as an attempt to write a introductory book about state management in React with Redux, turned out into a full blown page book which showcases MobX as alternative state management library, implements exciting applications along the way and has boilerplate projects to get you started in learning and building applications with these libraries.

React components can possess internal "state," a set of key-value pairs which belong to the component. When the state changes, React re-renders the component. Historically, state could only be used in class components. Using hooks, you can apply state to functional components too. In this example, the rendered text will always show the number in the component's state. Clicking the button will increment the value.

Optional Payload. However, you can apply the initial state on a more fine-grained level. Nowadays, state management is often used in modern applications. It says that a data structure is immutable when it cannot be changed. Please reach out to me to get a refund. So far, the payload was dumped without much thought in the actions. The View is basically the component tree Redux 46 in a modern application. The Dispatcher on the way delegates the Actions to the Store s. It could be a list of authors or the user object describing the user that is currently logged in to the application. So why did the bidirectional data flow fail? Again, not everything is mandatory, but you should at least know about the following things to embrace best practices, common usage patterns and practices on scaling your state architecture.

If there is not such a case, you return the unchanged state by default. The reducer takes care of the action. State gets updated by using this. Otherwise, the default substate from the createStore is used. Take for example the todoReducer that operates on a list of todos. The counter prop would be displayed and the two callback functions, onIncrement and onDecrement would be used for the buttons. As mentioned, the concept of local state should be known in other SPA solutions, too, and thus be applicable in those solutions. You can join the channel to get help or to help others. Your knowledge around state management will not only scale horizontally by using different techniques but also vertically by using technique on technique. Though it is possible to save props as state, there are little use cases. If you belong to a minority or are in an organization that supports diversity, please reach out to me. An Action would encapsulate all the necessary information to update the state in the Store s. That might not be the best approach in the first place, because you have to experience a problem before you use a solution for it. The reducer reduces - that explains the naming - the previous state and incoming action to a new state.
